Registration Authority

IEEE offers Registration Authority programs or registries which maintain lists of codes under standards and issue codes to those wishing to register them. Registration assigns unambiguous names to objects in a way which makes the assignment available to interested parties.

About the registration authority

The IEEE Registration Authority operates under the direction of the IEEE-SA Board of Governors. IEEE is recognized by ISO/IEC as the authorized Registration Authority to provide this service world-wide.

General Information
Background information about the Registration Authority and registries.

Registration Authority Committee (RAC)
Oversight committee that assists standard developing organizations to establish unambiguous, sustainable registration authorities.

Tutorials
Informative documents to assist with learning more about IEEE-SA Registries.

Credit Application Form
For those interested in paying for a registry via purchase order.

registries

Organizationally Unique Identifier (OUI)
An OUI can be used to create MAC Addresses, Bluetooth Device Addresses or Ethernet Addresses.

OUI-36
A 36-bit identifier that can be used as an Individual Address Block or as an extended OUI.

Individual Address Block (IAB)
For those who need less than 4,097 unique 48-bit numbers (EUI-48).

EtherType Field
Provides a context for interpretation of the data field of an Ethernet/IEEE 802.3 data frame (protocol identification).

Manufacturer ID
The manufacturer of a transducer is defined with a 14-bit code called the manufacturer ID.

Logical Link Control (LLC)
Contains addressing information that consists of the Destination Service Access Point (DSAP) and the Source Service Access Point (SSAP) address field.

Unique Registration Number (URN)
A 64-bit unique identifier contained in memory devices, or nodes, in which IEEE 1451.4 TEDS data is stored.

IEEE Template/TDL Item
IEEE template is a definition of the placement and significance of each piece of data stored within the TEDS memory. A TDL's purpose is to map bits.

Provider Service Identifier (PSID)
Used by IEEE 1609 standards to identify a particular application service provider that announces it is providing a service to potential users of an application or service.

IEEE 802.16 Operator ID
A 24-bit number that is broadcast by a base station as part of its Base Station ID.

Standard Group MAC Address
NOTE: For Standards Development use ONLY. A Universally Administered Address Block allocated for the assignment of Group MAC Addresses for use in Standards.
